Two suggestions:

1) Using the 'n' priority will make your dialplans more maintainable.

2) Using a more 'explicit' pattern like '_212555xxxx' will result in a 
more responsive dialplan* because Asterisk 'knows' it is looking for a 10 
digit number and won't have to 'wait' to see if it has the whole number. 
(For circuits that don't deliver the DID/DNIS all at once.)

Using an 'open ended' pattern could also expose you to unexpected 

Thanks in advance,
